At least they apparently decided not to roll their own display server. That would have been much much worse.

And I don't see anything wrong with SurfaceFlinger since it's already optimized for mobile. Wayland can stay on desktops and notebooks. AMD's Bridgman already claimed that the OSS graphics drivers should be workable on any display server.

I think they'll use SurfaceFlinger for desktop as well and this is the reason I won't support Ubuntu anymore.

So basically this whole thing is just android with unity interface on top of it? This isn't actually Ubuntu, more like android with ubuntu themes.

Then again, if you glue the ubuntu front-end on top of a different (but related) back-end, the result will still feel like ubuntu in most ways.
It's basically a philosophical question: Is the essence of ubuntu in the user experience, or in the underlying platform?

Chip vendors will make it if they'll feel compelled enough. Without the push - they won't move. And Ubuntu runs away from pushing - that was my point. Using Surface Flinger isn't good, since it means sticking with bionic libc. I.e. Ubuntu on mobile basically will be a separate thing, much closer to Android, than to normal Linux. Mer, Plasma Active and Sailfish in this context look much better and are pushing the stack which shares the effort with desktop Linux. Wayland will eventually come on mobile. Just probably without Canonical's help.

How hard would it be to port surfaceFlinger to gnu (or, just for the hell of it, FreeBSD) libc? I'm only guessing, but it seems like the complexity lies in the driver interactions, not in the libc calls - and porting from one libc to another ought to be surmountable anyway.

If it doesn't use Dalvik it isn't Android or just a theme for CynaogenMod.

It's funny how people in these forums start to moan and complain about things that are only in their own heads.

According to this post ubuntu touch *does not use bionic*, it uses libhybris which allows the use of android drivers with glibc.

So ubuntu touch is not that much of android, but not that much of GNU either, it is its own thing. With regard to the push for SurfaceFlinger on the desktop, we will have to wait and see. But the desktop and touch interfaces will most probably remain very different beasts for quite some time. Since X is all the desktop blobs support right now.

Before moaning about whatever display server canonical might be pushing, remember this one thing: *it must be supported by the blobs*. The only GPU more or less well supported by open drivers is intel's. All the other ARM SoCs or desktop GPUs require blobs, end of story. Consumers mostly buy notebooks, which should not melt when ubuntu is installed.

Either ubuntu gets big enough so that canonical can convince GPU makers to write drivers for their own display server, or they are bound to use the display servers (or a fork thereof) that is already supported by GPU makers.

That said, I do believe it would be easier to convince AMD/nVidia to support SurfaceFlinger than to convince *everyone* to support wayland (how are they so much different anyway?). If someone else does that or manages to write good open drivers for every GPU under the sun, then I'm sure canonical would reconsider.

Radeon is fairly well supported by the open drivers (excluding RadeonSI), but I'm just nitpicking.

That will depend on how things turn out. Personally, I don't really care what display server gets chosen as the de facto as long as it works, existing drivers still function without breaking, and existing applications get upstream changes to let them compile and run on the new display server. If Android's SurfaceFlinger gets blessed as the new de facto display server and Chrome / Firefox / LibreOffice / Skype / <insert any other X-based application here> are updated to include support for it, great.

Same for Wayland.

My only demand (which is fairly reasonable as a user) is that whatever the devs eventually choose as the de facto is to stick with it and stop flirting with alternatives for no good reason. Not like a certain person from a well-known distribution that got everybody all worked up over Wayland and caused so much development on it to take place only to do a 360 and now proclaim that "Wayland does not suit their needs and that they need to consider something else".

If you choose to stay with X, STAY WITH IT.
If you choose to migrate to Wayland / SurfaceFlinger / <insert other unheard-of display server>, MAKE SURE EVERYBODY ADOPTS IT.

The last thing I want is to see a webpage offering users a downloadable package that says "Download Application XYZ for a) X, b) Wayland, c) SurfaceFlinger".
